Last night I we were treated to photos of the debris of US and Soviet satellites falling to earth.
Gee how big is space, what are the sizes of satellites, what is the probability that will happen?
Now this morning we have news that a British and French nuclear powered nuclear armed subs have collided in the
Atlantic Ocean. Given the electronic navigation systems on these ships, well, outliers and Black Swans do happen don't they?
